OIL-PRESS MAT.

SPECIFICATION forming part of Letters Patent No. 790,607, dated May 23, 1905. Original application filed September 10, 1901, Serial No. 74,906. Divided and this application filed June 26, 1902. Serial No. 113,263.

To all whom. it 7771001/00711067'711.

Be it known that I, ROBERT FRANZ WERK, a citizen of the United States, and a resident of New Orleans, in the parish of Orleans and. State of Louisiana, have invented new and useful Improvements in Oil-Press Mats, of which the following is a full, clear, and exact description. The present improvement in oil-press mats is a division of an earlier application for Letters Patent filed September 10, 1901, Serial No. 74,906.

The improved mat is made of animal hair by weavingtogether threads or strands. in a well-known manner; and the distinguishing feature of the improvement resides in warpthreads made of soft hair. This overcomes the difficulty which is present more or less in all horsehair press-mats-namely, a liability to unravel. The desired strength and durability of the matis secured by the use of hard, stiff, and coarse hair in the production of the weft-threads.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a plan view of an oil-press mat embodying the present invention, and Fig. 2 is a longitudinal sectional elevation on the line 2 2 of Fig. 1.

As shown by the drawings, the mat or fabric consists of a plurality of longitudinal warp strands or' threads A and a series of weft threads or strands B, the latter extending transversely to the warp strands. Before weaving the fabric it is first necessary to select and prepare the proper kinds of hair for the production of different strands or threads, and in the present invention the warp-threads are made of soft pliable hair, while the weftthreads are composed of hard, stiff, and coarse hair. This combination of different kinds of hairs produces a mat or fabric which is entirely free from a tendency to unravel, and at the same time the article possesses the desirable features of pliability, durability, and good drainage of the oil through the same.

The soft hair for the production of the warp-threads is selected and arranged so as to be spun or twisted together into a thread of the desired length and thickness. The weft threads or strands are made of hard,

stiff, and coarse hair, which is properly selected and arranged so as to bespun and twisted into thread of thedesired length; but I prefer to make the weft threads or strands of increased thickness as compared with the thickness of the warp-strands.

The warp-strands are arranged in parallel relation and in the same transverse plane, while the weft-threads are interwoven with the warp-strands in a manner to be entirely concealed and protected thereby. (See Fig. 2.) The warp-strands greatly exceed in number per square inch the weft-threads, and in practice I prefer to use from five to eight times as many warp-strands as there are weftthreads in the fabric.

The arrangement of the warp-threads with relation to the weft-threads secures a more uniform distribution of the pressure over the weft-threads.

By the above-described construction a very strong and durable mat is produced. The weft-threads give to the mat great resisting power in a crosswise direction, therebyenabling the mat to resist the great lateral strain to which it is frequently subjected, and as the warp-threads have a tendency to spread and flatten out they not only form a cushion for protecting the weft-threads, but they will not cut into the weft-threads and injure the same,

as hard warps would do, and consequently the life of the mat is prolonged.

Having thus described my invention, I claim 'as new and desire to secure by Letters Patent 1. An oil-press cloth or mat consisting of warp-threads and weft-threads each made of long animal hair, each warp-thread consisting exclusively of soft pliable hair, and each weftthread being made of hard, stiff and coarse hair; the soft, pliable warp-threads forming the selvage of the mat.

2. An oil-press mat consisting of warpthreads and weft-threads each made of long animal hair; each warp-thread consisting exclusively of soft pliable hair, the warp-threads,

at the middle of the mat being made of longer hair than the Warp-threads at the selvage, and each Weft-thread being made of hard, stiff and coarse hair; the number of Warp-threads exceeding the Weft-threads per inch, and the Weftthreads being thicker than the Warpthreads. 1

In testimony whereof I have signed my 11 a1 n e to this specification in the presence of two subscribing Witnesses.
